Subject: [PATCH 2/2] Remove the obsolet driver for the DM9000E ethernet device
Date: Mon, 12 Dec 2011 12:21:21 +0100	[thread overview]
Message-ID: <1323688881-29140-3-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1323688881-29140-1-git-send-email-jbe@pengutronix.de>

Support for the old DM9000E device is now part of the new dm9k.c driver. So,
remove the old driver source and switch all users to the new driver.
